I am getting some "hiccups" in my audio and video signal, both on HD channels and SD channels. There's no pattern and it seems to happen sporadically at time. Sometimes it gets bad and happens every 45 seconds. They've sent me a new STB and that didn't solve the problem. They sent out a tech to check the signal strength and his equipments says signal is good. This happens on both the HDDVR and the regular STB, on different tvs, so it can't really be a hardware problem.
I'm thinking of installing this coax signal booster on the line, would there be any harm in doing this?
